the cowl on my motor says 125 but im not to sure thats what it is. i was looking at the fuel pump and it is not the one the 125 is shown to have on boats.net. it is the one the 120 and the 90 has(the square one).so what are the tell tail signs of what motor is on my boat? the plate on the trim says 1251x9b,what else should i look for??
